Pontiac Repair: grand am, code p0300, pontiac grand am

Question
A pontiac grand am 2.4l misfires error code p0300 b

Answer
Hi Tony:

P0300 is a dandon Misfire code. meaning that the engine is misfiring on multiple cylinders and not bad enough for the enine computer to pinpoint exactly which one is the worst. For example if #1 cylinder was misfiring only it would set a code p0301 #2 po302 etc... if it misforing on more than one cylinder I would look at fuel pressure or a spark issue. The housing the coils sit in on those engines go bad from time to time. Good luck :)
